The given is:Mass – 2000 kg
The given is:Mass – 2000 kgInstantaneous speed – 10 meter per second
Step: 1K.E= 1/2mv^2
Where, K.E – Kinetic energy in joules:
m – Mass in kg
v – Velocity or speed in meter per second
From the give,
m = 2000 kg
v = 10 m/s
Equation (1) becomes,
K.E= 1/2 (2000) (10)^2
= (0.5)(2000)(100)
= 100000
K.E = 100,000 Joules
The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s.
